Construction

Question 1

Bisecting a straight line

Answer 1

Draw an arc center P with the radius 1/2 PQ
Draw another arc center Q with the same radius
Label here the two arcs meet as X and Y
Join XY

Question 2

Bisecting an angle

Answer 2

Draw an arc center B
Label where the arcs meet each side of the angle X and Y.
Draw two arcs with the same radius centered at X and Y
Label the intersection of both arcs Z
Join BZ

Question 3

90° angle

Answer 3

Draw two arcs centered at X (1/2 the line AB) at both ends of line AB
Increase the radius
Draw arcs centered at A and B to intersect each other
Label that intersection P
Join X and P

Question 4

60° angle

Answer 4

Draw a large arc center x(half the line AB) to intersect with the end of the line at B
Draw an arc using the same radius center B to intersect with the first arc
Label that intersection Q
Join X and Q

Question 5

Parallel Lines

Answer 5

Join P to any Point on AB
Label that point Q
With Q as the center using any radius draw an arc intersecting with the lines PQ and AB
Label those points T and U
With P as the center and using the same radius draw an arc intersecting PQ
Label that point V
Using the radius equal to the distance of TU draw another arc
Label the point of intersection W
Draw a line through P and W
